HEATING-FURNACE.

SPECIFICATION forming part of Letters Patent No. 368,201, dated August16,1887.

Application filed March 17, 1887.

To all whom it may concern/H Be it known that we, OLNEY B. FULLER andXVILLIAM M. \VYCKOFF, of Detroit, in the county of lVayne and State ofMichigan, have invented new and useful Improvements in Heating-Furnaces;and we do hereby declare that the following is a full, clear, and exactde scription thereof, reference being had to the accompanying drawings,which form a part of this specification.

This invention relates to that class of furnaces wherein are combinedthe systems of hot-air and hot-water circulation for heating purposes;and the object of the invention is to construct a device for thispurpose in a simple, cheap, and efficient manner, and that can bereadily applied as an attachment to various styles of furnaces now inuse.

The invention consists in the peculiar eonstruction, arangement, andcombinations of the various parts, all as more fully hereinafter setforth.

Figure l is a central vertical section of our improved furnace. Fig. 2is a perspective of the reservoir detached. Fig. 3 is a top plan of thedistributingchamber. Fig. 4 is a similar view of the top of thereservoir.

In the accompanying drawings, which form a part of this specification, Arepresents a suitable base, which is provided with the usual firepot B,and ash-pit O, and may be of any of the known constructions.

Upon the top of the tire pot section is mounted the firebox D orcombustion-chamber, preferably made of boiler-iron and provided with thefeed-door E. The bottom of this fire-box should be lined withfire-brick, as shown. Near the top the fire-box is provided with aninwardly-projecting flange, (4.

F is a reservoir somewhat smaller in diameter than the fire-box, and isprovided with the vertical fines I), the reservoir being c0n struetedupon the principle of a vertical-flue boiler. Mounted upon thisreservoir F, and having communication with the water-space thereof bymeans of the pipes c, is a distributing-chamber, (3, through whichpasses a central flue, H. This distributing-chamber is provided with aflange, I, designed to fit closely in the upper end of the tire-box andrest upon Serial No. 231,250. (No model.)

its flange a, and at which point a sand or other suitable gas-tightjoint should be made.

J is a jacket which surrounds the fire-box, and is provided with anopening, K, coincident with the feed-door E of the fire-box, the smokeand products of combustion of the latter passing up through the verticalilues of the reservoir and over the top thereof to the flue H, andthrough the distributing-chamber to a proper exit pipe, which conductsthem to the chimney.

L are suitable pipes rising from the distributing-chamber G, such pipesbeing employed for conducting the water to such, room or rooms as it isdesired to heat'by hot-water circulation, the return to the boiler beingthrough a pipe, M. Hot-air pipes N convey the heated air from the jacketJ to the desired points.

The reservoir should be provided with any convenient expansion-chamber,as is required in all systems of hot water circulation for heatingpurposes.

It will be observed that the dues of the reservoir F are arranged mainlyin a circle near the outer edge thereof, while pipes communieating withthe distributing chamber are grouped near the center, thedistributingpipes from the chamber G being located near its outer edge.This arrangement of pipes and fines assures a better circulation throughthe boiler or reservoir.

In practice, the parts being constructed and arranged substantially asshown, a fire being built in the furnace, the products of combustionpass up through the ilues of the reservoir, over the top of the same,and thence through the central flue of the distributirig-chamber, fromwhence they find exit to the chimney throughasuitable pipe. Thisnecessarily high- 1 y and quickly heats the water in the reservoir,which is then circulated through the distributing-chamber and pipes, andreturned to the boiler, as in all systems of this class of heat ing. Theheat that is radiated from the firebox heats the air within the outerjacket, such heated air being distributed to the desired points byproper pipes. There is a space left between the outer wallsof thereservoir and the walls of the fire-box, into which space heatnecessarily rises, and thereby greatly increasing the utility of thedevice both in heating the water in the reservoir and in radiating heatinto the jacket.

It will readily be seen that the reservoir can be advantageously used asan attachment to any of that class of furnaces wherein there is a domeover the fire-pot, as in all of the so called surface burners.

' What we claim as our invention is 1. The combination, with thefire-box provided with inwardly-projecting flange a,of thedistributing-chamber formed with a flange, I, designed to rest upon theflange a, the reservoir F, arranged beneath said distributingchamber andprovided with vertical flu'es b, the pipes a, connecting said reservoirand chamber, and a central flue, H, passing through said chamber,substantially as and for the purpose specified.

2. The combination, with the fire-box,of the I
